Title: Anode catalyst for polyelectrolyte type fuel cell and its preparation
Inventor: WATANABE MASAHIRO
IPC: H01M4/90
Filed: 1995-12-04
Abstract: PROBLEM TO BE SOLVED: To provide an anode catalyst having the composition range different from that of a cathode catalyst for a fuel cell having the conventional platinum- iron alloy phase, excellent in poisoning resistance characteristic against carbon monoxide, rarely having elution, and having a long life. SOLUTION: A platinum-iron alloy phase containing platinum of 84-99 atomic % and iron of 1-16 atomic % is carried on a catalyst carrier. This alloy phase may contain a noble metal selected from palladium, ruthenium, rhodium, and gold. An anode catalyst containing iron of 1-16 atomic % doesn't generate FePt3 generated by the anode catalyst containing iron in the range exceeding 16 atomic %, inferior in poisoning resistance characteristic, and liable to cause deterioration due to elution, thus it has a longer life than before.

Title: Bath hot water supplying device with waste heat recovery function and method of recovering waste heat for supplying hot water
Inventor: HIRATA TOSHIAKI
IPC: F24H1/00
Filed: 1994-12-28
Abstract: PURPOSE: To utilize heat recovered effectively by recovering waste heat of hot water left in a bathtub as discarded without being re-used in the past. CONSTITUTION: In the recovery of waste heat, a controller 4 sends a signal to three-way valves 31 and 32 and makes the valves 31 and 32 open to get a pipeline 30 for recovering waste heat, a pipeline 13a and an outgoing circulation pipe 16 communicate with one another. As a result, hot water left in a bathtub 17 reaches the pipeline 30 for recovering waste heat via the first three- way valve 31 from the return circulation pipe 16 and it undergoes a heat exchange with city water flowing through the pipeline 8a in a water-water heat exchanger 33 arranged in the course of the pipeline 30 for recovering waste heat. With the heat exchange, the city water is heated. The city water heated is reheated with a hot water heat exchanger 5 and then, the hot water is supplied at a hot water cock 1.

Title: Device and method for automatic program generation
Inventor: NODA NATSUKO
IPC: G06F9/06
Filed: 1996-12-19
Abstract: PROBLEM TO BE SOLVED: To provide an automatic program generation device which can deal with the extension of an input specification form or the change of style of an output program without correcting a conversion rule. SOLUTION: An input/output correspondence table 122 which shows the corresponding relation between the input and the output and a template 123 which shows a general pattern of the output are placed outside a program generation part 121. Then a table retrieval rule which retrieves the table 122 and a template expansion rule which expands the template 123 are defined as a meta-rule 1212. The relation between the input specification and an output program can be freely changed without re-forming the part 121 since the relation is defined outside the part 121. The retrieval of the table 122 and the expansion of the template 123 are carried out based on the meta-rule 1212. Thus it is not required to correct a conversion rule even if the extension of an input specification form or the change of style of an output program is required.

Abstract: PURPOSE:To simply separate a melt resin from a set part by a method wherein a partition plate facing a resin path of a hot runner manifold at one surface thereof and facing a cavity at the other surface thereof is provided on a suck- back rod, and the suck-back rod is moved forward and backward. CONSTITUTION:A resin is injected into a cavity 7 from a molding machine nozzle 4 through a resin path 2 in a manifold 1. After the resin is cooled, the amount of a resin to be next injected into the cavity 7 is measured. When the resin in the resin path 2 comes to a parallel state, air is fed into an air cylinder 11. The other end of an arm 9 is lifted by a piston 12. In this manner, air in an air chamber 8b is extruded, and a suck-back rod 8 is moved backward until a partition plate 8b comes into contact with the manifold 1. At this time, the resin also moves upward by the resistance of a top end 8c of the rod 8. A melt resin in the vicinity of a gate part 1b is also pulled up to be separated from the molded piece in a set state in the cavity 7. Therefore, the separation is ensured by such a simple construction.

IPC: G06K9/68
Filed: 1997-12-11
Abstract: PROBLEM TO BE SOLVED: To prepare a learning character image of low quality in a range allowed to be identified by human observation. SOLUTION: A learning image preparing part 3 sets up n pieces of binary thresholds between a blurred image preparing threshold and a distorted image preparing threshold. The size of n pieces of images obtained by binarizing a malti-valued character image by n pieces binarizing thresholds is compared with that of an optimum binary image obtained by binarizing the multi-valued character image by an optimum binarizing threshold, and when both the sizes are not sharply different, the character image is adopted as a learning image. A noise removing part 8 compares the learning image with the optimum binary image, removes noises from the learning image and outputs the noise-removed learning image to a memory 9.
